Astronomy 101 Exam Unc questions and Verified
Answers
kirkwood gaps - ANSWER Jupiter's strong gravity makes asteroid orbits within Jupiter's orbit
unstable
kirkwood gaps - ANSWER reason why the asteroids didn't form a separate planet
asteroids - ANSWER small, airless, rocky worlds revolving around the sun that are too small to
be called planets. most have an irregular shape and elliptical orbits
jovian planets - ANSWER the internal structures contain rock, metal, and hydrogen compounds
jupiter and saturn - ANSWER metallic, liquid, and gaseous hydrogen are the main components
of these 2 planets' internal structures
uranus and neptune - ANSWER water, methane, ammonia, and gaseous hydrogen are the main
components of these 2 planets' internal structures
jupiter - ANSWER planet that most resembles the sun
jovian planets - ANSWER compositions are made up of mostly hydrogen and helium, very
similar to the sun
great red spot - ANSWER giant spinning storm on Jupiter's atmosphere that exceeds more than
2 times the size of the earth and has winds over 270 mph
great dark spot - ANSWER giant spinning storm in Neptune's southern atmosphere that is about
the size of the earth and as wind speeds up to 1500 mph (fastest in solar system)
, jupiter - ANSWER has largest planetary atmosphere in solar system and is made up mostly of
hydrogen and helium
gas giants - ANSWER include Jupiter and Saturn and are primarily composed of hydrogen and
helium with a thick layer of metallic hydrogen and a molten rocky core - can't land on these
planets
ice giants - ANSWER include Neptune and Uranus and are massive planets composed mainly of
substances heavier than hydrogen and helium
ring system - ANSWER bands of orbiting dusty particles and ice balls
jupiter - ANSWER planet whose ring system includes faint, dusty rings
saturn - ANSWER planet whose ring system includes bright, spectacular rings
uranus - ANSWER planet whose ring system includes dark, thin rings
neptune - ANSWER planet whose ring system includes dark, thin rings and ring arcs
moon - ANSWER ours, orbits close to the ecliptic plane
triton - ANSWER moon of neptune, has a retrograde orbit, composition similar to pluto,
geologically active - geysers erupting nitrogen gas
titan - ANSWER moon of saturn, dense atmosphere and stable bodies of surface liquid,
composed of water ice and rocky material with nitrogen atmosphere
